The choice of M and N depends on the visibility of the objects. This groundbreaking technology is already making driving safer for thousands of Americans with equipped cars. There are 3 cases of FCW: Safe (green): There is no car in the ego lane (no MIO), the MIO is moving away from the car, or the distance to the MIO remains constant. The biggest myth about ADAS systems is that they are self-sufficient, or will alert you when the system is not calibrated properly. Forward Collision Alert can warn you if it detects a potential collision with a detected vehicle youre following so you can take action. Always nice to be proven right. Note that this distance varies with the relative speed between the MIO and the car, and is greater when the closing speed is higher. Honda offers FCW on select models as part of its Honda Sensing package. If you get too close to the vehicle in front of you, the FWC will alert you with lights and sound. Forward Obstruction Warning (FOW) is a system which alerts the driver of a possible collision using an indicator and warning sound in the instrument cluster while the vehicle is being driven at about 15 km/h or faster (10 mph or faster) and the system's radar sensor determines that your vehicle may hit a vehicle or obstruction ahead.
